Abstract

The inner body (14) forms a sleeve (37) developing externally through a shoulder (36) to a flange (28) seated on the rim of a similarly shaped orifice (O) in the partition-plate (P). Below the flange, a skirt (39), with external guiding wedges (32), projects through the orifice. The sleeve's internal aperture (20) accepts the e.g. rectangular section bar connector with minimal clearance. A pin through (40) the sleeve wall and a corresponding hole in the bar locates the latter axially. The web-stiffened (56) outer cover (16), like the body moulded in e.g. polyamide with a protective coating, fits closely over the body, clamping it against the plate, its flat base (52) having fixing holes at each corner (54). A peripheral seal (68) round the body flange ensures a tight joint between the main components and between each and the plate; a second seal (72) similarly seals sleeve end, cover and bar. A collar (18) forming a shed, snap-fitted on the end of the cover, has a resilient lip (26) sealing it to the bar connector.

Description

La présente invention concerne un dispositif passe-barre, destiné à être monté au travers d'un orifice ménagé dans une paroi pour le passage d'une barre conductrice, du type comportant un corps traversé de part en part par un conduit de réception de ladite barre et une couvercle rapporté sur ledit corps, ledit couvercle comportant, pour le passage de ladite barre, une lumière qui prolonge le conduit du corps.The present invention relates to a bar pass device, intended for be mounted through an opening in a wall for passage of a conductive bar, of the type comprising a body traversed right through leaves by a conduit for receiving said bar and an attached cover on said body, said cover comprising, for the passage of said bar, a light that extends the body's duct.

Elle concerne en outre une traversée de paroi.It also relates to a wall crossing.

Les dispositifs passe-barre sont destinés à permettre le passage d'une ligne électrique, notamment de forte intensité, au travers d'une paroi, par exemple la paroi du boítier d'un transformateur.Bar pass devices are intended to allow passage an electrical line, particularly of high intensity, through a wall, for example the wall of the housing of a transformer.

Les traversées de paroi sont ainsi réalisées à partir d'un dispositif passe-barre et d'une barre conductrice. Pour les barres de section oblongue et notamment sensiblement rectangulaire, les dispositifs passe-barre sont actuellement réalisées en matière plastique. Les traversées de paroi doivent être utilisées sous un capot ou dans une pièce à l'écart des intempéries extérieures, les matières utilisées, dans les structures connues, n'offrant pas une bonne résistance aux agressions extérieures. En particulier, les dispositifs passe-barre n'assurent pas une étanchéité suffisante.The wall crossings are thus produced from a device bar pass and a conductive bar. For oblong section bars and notably substantially rectangular, the bar pass devices are currently made of plastic. Wall crossings must be used under a hood or in a room away from the weather materials used in known structures that do not offer good resistance to external aggressions. In particular, bar pass devices do not provide sufficient sealing.

Les traversées connues qui supportent une exposition aux intempéries extérieures comportent des dispositifs passe-barre, appelés dans ce cas passe-tige, réalisés en porcelaine. Ces dispositifs passe-tige, du fait de leur mode de fabrication, ne permettent que le passage d'une tige conductrice de section circulaire. De plus, ils sont coûteux. Enfin, ils sont fragiles et ne supportent pas des flexions trop importantes de la tige conductrice.Known crossings that support exposure to outdoor weathering includes bar pass devices, called in this case rod holder, made of porcelain. These rod-pocket devices, because of their manufacturing method, only allow the passage of a rod conductor of circular section. In addition, they are expensive. Finally, they are fragile and do not support excessive bending of the rod conductive.

L'invention a pour but de proposer un dispositif passe-barre, de faible coût, pouvant être exposé aux intempéries extérieures, et permettant de recevoir une barre de section oblongue, notamment rectangulaire.The object of the invention is to provide a low-pass bar device cost, which can be exposed to outdoor weather, and allows receive an oblong section bar, in particular rectangular.

A cet effet, l'invention a pour objet un dispositif passe-barre, du type précité, caractérisé en ce que la lumière du couvercle est bordée extérieurement par une lèvre périphérique déformable élastiquement, adaptée pour s'appliquer de manière étanche sur tout le contour de la barre conductrice.To this end, the invention relates to a bar pass device, of the type aforementioned, characterized in that the cover light is bordered externally by an elastically deformable peripheral lip, adapted to apply tightly over the entire contour of the bar conductive.

Suivant des modes particuliers de réalisation, le dispositif passe-barre comporte l'une ou plusieurs des caractéristiques suivantes :

  • la lèvre est venue de matière avec au moins une partie du couvercle;
  • le couvercle comporte une structure rigide interne et la lèvre est surmoulée sur ladite structure rigide;
  • la lèvre est venue de matière avec un revêtement isolant recouvrant au moins l'essentiel de la surface externe du couvercle;
  • ledit passage et la lumière ont des sections sensiblement identiques de forme oblongue;
  • le corps comporte, dans une région recouverte par le couvercle, un perçage transversal débouchant dans ledit passage, lequel perçage est adapté pour la réception d'une goupille de retenue de la barre conductrice qui comporte elle-même un perçage pour l'extrémité de la goupille, le couvercle rapporté sur le corps emprisonnant la goupille;
  • le corps comporte une collerette périphérique d'appui sur une face de la paroi, le couvercle comporte des moyens de fixation sur la paroi et présente une forme de coiffe recouvrant à la fois l'essentiel du corps et la collerette périphérique, et un joint annulaire est disposé autour de la collerette périphérique, contre la paroi, dans un logement du couvercle;
  • le couvercle comporte un logement de réception de l'essentiel du corps, ce logement étant prolongé par la lumière, et le logement comporte, sur au moins une partie de sa longueur, un tronçon de section progressivement décroissante vers la lumière adapté pour le guidage et la compression dans le logement d'un joint annulaire interposé entre le corps et le couvercle lors du montage du couvercle sur le corps.
According to particular embodiments, the bar pass device comprises one or more of the following characteristics:
  • the lip came integrally with at least part of the cover;
  • the cover has an internal rigid structure and the lip is overmolded on said rigid structure;
  • the lip has come in one piece with an insulating coating covering at least most of the external surface of the cover;
  • said passage and the light have substantially identical sections of oblong shape;
  • the body comprises, in a region covered by the cover, a transverse hole opening into said passage, which hole is suitable for receiving a pin for retaining the conductive bar which itself has a hole for the end of the pin, the cover attached to the body trapping the pin;
  • the body has a peripheral support flange on one face of the wall, the cover has means for fixing to the wall and has a cap shape covering both most of the body and the peripheral flange, and an annular seal is arranged around the peripheral flange, against the wall, in a housing of the cover;
  • the cover includes a housing for receiving most of the body, this housing being extended by the light, and the housing comprises, over at least part of its length, a section of progressively decreasing section towards the light suitable for guiding and compression in the housing of an annular seal interposed between the body and the cover when the cover is mounted on the body.

L'invention a en outre pour objet une traversée de paroi, caractérisée en ce qu'elle comporte une barre conductrice et un dispositif passe-barre tels que définis ci-dessus.The invention further relates to a wall crossing, characterized in that it comprises a conductive bar and a bar pass device as defined above.

L'invention sera mieux comprise à la lecture de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins sur lesquels :

  • La figure 1 est une vue en coupe de trois-quarts d'une traversée de paroi selon l'invention ; et
  • La figure 2 est une vue en perspective, partiellement en coupe, du dispositif passe-barre de la traversée de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the drawings in which:
  • Figure 1 is a three-quarter sectional view of a wall crossing according to the invention; and
  • FIG. 2 is a perspective view, partially in section, of the bar pass device of the crossing in FIG. 1.

La traversée représentée sur la figure 1 comporte un dispositif passe-barre 10 et une barre conductrice 12. Le dispositif passe-barre 10 comporte un corps 14 et un couvercle 16 muni, au sommet, d'une collerette externe 18. The crossing shown in Figure 1 includes a bar pass device 10 and a conductive bar 12. The bar pass device 10 comprises a body 14 and a cover 16 provided, at the top, with an external flange 18.

En variante, le couvercle 16 peut comporter au sommet plusieurs collerettes empilées suivant une partie de la longueur de la barre conductrice 12.As a variant, the cover 16 may include at the top several flanges stacked along part of the length of the bar driver 12.

Le corps 14 et le couvercle 16 ont des formes sensiblement axisymétriques par rapport à la direction longitudinale de la barre 12. Ils sont réalisés essentiellement en une matière thermoplastique, par exemple du polyamide, du polybutylène téréphtalate ou du " peek ". La surface externe ou exposée du couvercle 16 est en outre recouverte totalement d'un revêtement protecteur et isolant 19.The body 14 and the cover 16 have shapes substantially axisymmetric with respect to the longitudinal direction of the bar 12. They are essentially made of a thermoplastic material, for example polyamide, polybutylene terephthalate or "peek". The outer surface or exposed cover 16 is further completely covered with a protective and insulating coating 19.

La barre conductrice 12 est rectiligne et a une section oblongue, par exemple rectangulaire avec ses petits côtés arrondis. Elle est réalisée en métal non ferreux et comporte à chaque extrémité des perçages pour la connexion de câbles électriques.The conductive bar 12 is straight and has an oblong section, for example rectangular example with its small rounded sides. It is carried out in non-ferrous metal and has holes at each end for the connection of electrical cables.

Le corps 14 est traversé de part en part par un conduit 20 de réception de la barre conductrice 12.The body 14 is traversed right through by a conduit 20 of reception of the busbar 12.

Le couvercle 16 présente une forme de cloche et délimite intérieurement un logement 22 de réception de l'essentiel du corps 14. Le logement 22 se prolonge à l'extrémité supérieure du couvercle 16 par une lumière 24 de passage de la barre conductrice 12. Cette lumière a une section sensiblement égale à la section de la barre 12.The cover 16 has a bell shape and delimits internally a housing 22 for receiving most of the body 14. The housing 22 is extended at the upper end of the cover 16 by a light 24 for passage of the busbar 12. This light has a section substantially equal to the section of the bar 12.

La lumière 24 est bordée extérieurement par une lèvre périphérique 26 déformable élastiquement, adaptée pour s'appliquer de manière étanche sur le contour de la barre conductrice 12. La lèvre 26 est venue de matière avec le revêtement 19 couvrant le couvercle 16.The light 24 is bordered externally by a peripheral lip 26 elastically deformable, adapted to be applied tightly on the contour of the conductive bar 12. The lip 26 has come in one piece with the covering 19 covering the cover 16.

Le corps 14 et le couvercle 16 sont adaptés pour être disposés comme représenté sur les figures 1 et 2 d'un même côté d'une paroi P traversée d'un orifice O.The body 14 and the cover 16 are adapted to be arranged as shown in Figures 1 and 2 on the same side of a wall P crossing an orifice O.

A cet effet, le corps 14 présente essentiellement la forme d'un manchon dont le conduit interne 20 est de section constante. La section interne du conduit 20 est très légèrement supérieure à la section de la barre conductrice 12.To this end, the body 14 essentially has the form of a sleeve whose internal duct 20 is of constant section. The section internal of conduit 20 is very slightly greater than the cross section of the bar driver 12.

Le corps 14 comporte extérieurement dans sa partie médiane une collerette 28 d'appui sur la surface externe de la paroi P. Cette collerette sépare axialement le corps en une partie destinée à traverser la paroi P et une partie destinée à être reçue dans le couvercle 16.The body 14 has externally in its middle part a flange 28 bearing on the external surface of the wall P. This flange axially separates the body into a part intended to pass through the wall P and a part intended to be received in the cover 16.

Du côté de la collerette 28 destinée à traverser l'orifice O et à faire saillie à l'intérieur du logement délimité par la paroi P, le corps 14 comporte un collet 30. Celle-ci délimite le passage 20. Ce collet est rigidifié extérieurement par des nervures longitudinales 32 régulièrement réparties sur sa périphérie.On the side of the flange 28 intended to pass through the orifice O and to make projecting inside the housing delimited by the wall P, the body 14 comprises a collar 30. This defines the passage 20. This collar is stiffened externally by longitudinal ribs 32 regularly distributed on its periphery.

Les nervures 32 sont de hauteur progressivement décroissante depuis la collerette 28 jusqu'à l'extrémité libre du collet 30, afin d'assurer un guidage du corps 14 dans l'orifice O lors de son introduction. De plus, au voisinage immédiat de la collerette 28, la hauteur des nervures 32 est inférieure à la largeur de la collerette 28, de sorte qu'une surface d'appui périphérique 34 est ménagée entre les nervures 32 et le contour extérieur de la collerette 28.The ribs 32 are of progressively decreasing height from the collar 28 to the free end of the collar 30, in order to ensure a guiding the body 14 in the orifice O during its introduction. In addition, at immediate vicinity of the flange 28, the height of the ribs 32 is less than the width of the flange 28, so that a bearing surface peripheral 34 is formed between the ribs 32 and the outer contour of the collar 28.

De l'autre côté de la collerette 28, le corps 14 est défini par un prolongement tubulaire 34 de section oblongue délimitant le conduit 20. Dans sa région de liaison avec la collerette 28, le prolongement tubulaire 34 comporte extérieurement une surépaisseur périphérique 36. Cette dernière est reliée à la partie courante, notée 37, du prolongement 34 par un tronçon d'épaisseur progressivement décroissante 38 formant un chanfrein périphérique. Dans l'exemple décrit, ce tronçon 38 est sensiblement tronconique.On the other side of the flange 28, the body 14 is defined by a tubular extension 34 of oblong section delimiting the conduit 20. In its region of connection with the collar 28, the tubular extension 34 externally has a peripheral allowance 36. The latter is connected to the current part, noted 37, of the extension 34 by a section of gradually decreasing thickness 38 forming a chamfer peripheral. In the example described, this section 38 is substantially tapered.

Un perçage radial 40 est ménagé sur une face plane du prolongement 34 dans sa partie courante 37 d'épaisseur réduite. Ce perçage 40 débouche à l'intérieur du conduit 20. Il est adapté pour recevoir l'extrémité d'une goupille, non représentée, destinée à la retenue axiale de la barre 12. L'autre extrémité de la goupille est reçue dans un perçage 42 transversal de la barre, aligné avec le perçage 40.A radial bore 40 is formed on a flat face of the extension 34 in its running part 37 of reduced thickness. This hole 40 opens into the interior of conduit 20. It is adapted to receive the end of a pin, not shown, intended for the axial retention of the bar 12. The other end of the pin is received in a bore 42 crossbar, aligned with hole 40.

Le couvercle 16 est formé, afin de faciliter son moulage, de deux parties enclenchées élastiquement l'une dans l'autre. Ainsi, il comporte un tronc 16A coiffant le corps 14 et une bague annulaire rapportée 16B définissant la collerette 18.The cover 16 is formed, in order to facilitate its molding, of two parts snapped together. So it has a trunk 16A covering the body 14 and an added annular ring 16B defining the collar 18.

Le tronc 16A comporte une paroi tubulaire 50 entourant le prolongement tubulaire 34. Cette paroi tubulaire 50 comporte, à son extrémité inférieure en contact avec la surface externe de la paroi P, une base de fixation 52 Elle porte, à son autre extrémité, la collerette 18.The trunk 16A has a tubular wall 50 surrounding the tubular extension 34. This tubular wall 50 comprises, at its lower end in contact with the external surface of the wall P, a fixing base 52 It carries, at its other end, the flange 18.

La base 52 est de forme sensiblement rectangulaire avec des coins arrondis. Dans les coins sont ménagés des perçages 54 pour la réception de boulons de fixation.The base 52 is of substantially rectangular shape with corners rounded. In the corners are provided holes 54 for the reception of fixing bolts.

Des nervures de renfort 56, de forme triangulaire, relient la surface exposée de la base 52 à la paroi tubulaire 50. Les nervures 56 prennent naissance à la base de la collerette 18. Elles ont une hauteur progressivement croissante jusqu'à la base 52. Reinforcement ribs 56, of triangular shape, connect the surface exposed from the base 52 to the tubular wall 50. The ribs 56 take birth at the base of the collar 18. They have a height gradually increasing to base 52.

Le tronc 16A est recouvert extérieurement sur toute sa surface exposée par une partie notée 19A du revêtement recouvrant l'ensemble du couvercle 16.The trunk 16A is covered externally over its entire surface exposed by a part denoted 19A of the covering covering the entire cover 16.

La collerette 18 a un contour extérieur oblong, sensiblement en forme d'ovale. Elle est légèrement inclinée vers la base 52 et s'étend sensiblement sur l'essentiel de la surface de celle-ci.The collar 18 has an oblong outer contour, substantially shaped oval. It is slightly inclined towards the base 52 and extends substantially on most of its surface.

La collerette est formée par la bague annulaire 16B recouverte d'une partie notée 19B du revêtement 19.The collar is formed by the annular ring 16B covered with a part denoted 19B of the covering 19.

La bague annulaire 16B comporte une jupe 57 délimitant partiellement la lumière 24 pour le passage de la tige 12. Cette jupe est reçue dans un lamage 58 ménagé à l'extrémité ouverte de la partie de la lumière 24 délimitée par le tronc 16A. La jupe 57 présente à son extrémité reçue dans le lamage 58 un bourrelet périphérique externe 59 adapté pour s'engager élastiquement dans une gorge annulaire complémentaire creusée dans le tronc 16A.The annular ring 16B comprises a skirt 57 delimiting partially the light 24 for the passage of the rod 12. This skirt is received in a counterbore 58 formed at the open end of the part of the light 24 delimited by the trunk 16A. The skirt 57 has at its end received in the counterbore 58 an external peripheral bead 59 adapted for to engage elastically in an additional annular groove dug in the trunk 16A.

A son autre extrémité, la jupe 57 est bordée par une couronne externe 60 s'étendant radialement. Cette couronne 60 constitue une âme rigide pour la collerette 18, cette dernière étant formée pour le reste par le revêtement 19B.At its other end, the skirt 57 is bordered by a crown outer 60 extending radially. This crown 60 constitutes a soul rigid for the flange 18, the latter being formed for the rest by the coating 19B.

La lèvre déformable 26 est constituée d'un bourrelet externe bordant la lumière 24. Ce bourrelet présente au sommet une arête vive 26A définissant une crête périphérique limitant la zone d'appui sur la barre conductrice 12. L'arête vive 26A se trouve dans le prolongement de la surface interne de la jupe 57 délimitant la lumière 24.The deformable lip 26 consists of an outer bead bordering the light 24. This bead has a sharp edge 26A at the top defining a peripheral ridge limiting the support area on the bar conductive 12. The sharp edge 26A is in the extension of the internal surface of the skirt 57 delimiting the light 24.

Le logement 22 du couvercle présente une section progressivement décroissante depuis la base 52 jusqu'à la lèvre déformable 26. Dans sa partie courante, le logement 22 comporte un tronçon principal 61 dont la section est très légèrement supérieure à celle du prolongement tubulaire 34.The housing 22 of the cover has a section progressively decreasing from base 52 to deformable lip 26. In its main part, the housing 22 comprises a main section 61, the section is very slightly greater than that of the tubular extension 34.

Au niveau de la base 52, le tronçon principal 61 est prolongé par un tronçon élargi 62 destiné à recevoir la surépaisseur 36 du corps. Le tronçon élargi 62 est relié au tronçon principal 61 par un tronçon de section progressivement décroissante 63 présentant un profil sensiblement tronconique convergeant vers le sommet du couvercle 16. Ce tronçon définit un chanfrein correspondant au chanfrein défini par le tronçon 38.At the base 52, the main section 61 is extended by a widened section 62 intended to receive the extra thickness 36 of the body. The section widened 62 is connected to the main section 61 by a section section gradually decreasing 63 having a profile substantially frustoconical converging towards the top of the cover 16. This section defines a chamfer corresponding to the chamfer defined by the section 38.

A son extrémité débouchante au travers de la base 52, le logement 22 présente deux lamages successifs 64, 66 destinés, pour le moins large. à recevoir la collerette 28 et, pour le plus large, à recevoir à la fois la collerette 28 et un joint d'étanchéité 68 disposé autour de celle-ci. Ce joint 68 est adapté pour venir en appui simultanément sur le couvercle 16, le corps 14 et la surface externe de la paroi P.At its end opening through the base 52, the housing 22 has two successive counterbores 64, 66 intended, to say the least. to receive the flange 28 and, for the largest, to receive both the flange 28 and a seal 68 disposed around it. This joint 68 is adapted to bear simultaneously on the cover 16, the body 14 and the external surface of the wall P.

Le tronçon principal 58 a une longueur supérieure à la longueur du prolongement tubulaire 34. Il s'achève au niveau de la lumière 24 qui définit avec le tronçon 58 un épaulement 70.The main section 58 has a length greater than the length of the tubular extension 34. It ends at the lumen 24 which defines with the section 58 a shoulder 70.

Un joint d'étanchéité annulaire 72 est disposé entre l'épaulement 70 et l'extrémité avant du prolongement tubulaire 34. Ce joint 72 est adapté pour s'appliquer simultanément sur le corps 14, le couvercle 16 et la barre conductrice 12 lorsque celle··ci est maintenue dans le dispositif passe-barre, comme représenté sur la figure 1. En variante non représentée, le joint unique 72 est remplacé par plusieurs joints empilés.An annular seal 72 is disposed between the shoulder 70 and the front end of the tubular extension 34. This joint 72 is adapted to apply simultaneously to the body 14, the cover 16 and the bar conductive 12 when it is held in the bar pass device, as shown in Figure 1. In a variant not shown, the seal single 72 is replaced by several stacked joints.

Selon l'invention, la lèvre 26 est réalisée en un matériau déformable, par exemple un élastomère isolant tel que du " silicone ", du " néoprène " ou du "nitrile". En particulier, la lèvre 26 est venue de matière avec le revêtement 19B recouvrant la bague annulaire du couvercle. Ainsi, le couvercle 16 est formé par une structure rigide interne, réalisée par exemple en matière plastique rigide sur laquelle est surmoulée la lèvre 26, en bordure de la lumière 24. La lèvre 26 se prolonge ainsi sur la collerette 18 et sur l'ensemble de la surface externe du couvercle 16 par l'intermédiaire du revêtement isolant 19A.According to the invention, the lip 26 is made of a deformable material, for example an insulating elastomer such as "silicone", "neoprene" or "nitrile". In particular, the lip 26 came integrally with the coating 19B covering the annular ring of the cover. So the cover 16 is formed by an internal rigid structure, made for example in rigid plastic material on which the lip 26 is molded, in border of the light 24. The lip 26 thus extends on the flange 18 and on the entire outer surface of the cover 16 via the insulating coating 19A.

Afin d'assurer le montage d'une telle traversée, la barre conductrice 12 est introduite au travers du passage 20. Elle y est immobilisée par mise en place d'une goupille non représentée introduite dans les perçages alignés 40 et 42. On introduit ensuite le corps 14 au travers de l'ouverture O. Le joint 68 est mis en place autour de la collerette 28 en contact avec la surface externe de la paroi P.In order to ensure the mounting of such a crossing, the conductive bar 12 is introduced through passage 20. It is immobilized there by putting in place of a not shown pin inserted in the holes aligned 40 and 42. The body 14 is then introduced through the opening O. The seal 68 is placed around the flange 28 in contact with the external surface of the wall P.

De même, le joint 72 est introduit à l'intérieur du logement 22 ménagé dans le couvercle 16. Plus précisément, le joint 72 est disposé temporairement dans le tronçon 62 de largeur légèrement supérieure au tronçon principal 61.Likewise, the seal 72 is introduced inside the housing 22 provided in the cover 16. More specifically, the seal 72 is arranged temporarily in section 62 of width slightly greater than main section 61.

Le couvercle 16 est alors rapporté autour de la barre 12 et de la partie extérieure du corps 14. Lors de l'enfoncement du couvercle 16 sur le prolongement tubulaire 34, le joint annulaire 72 est progressivement enfoncé suivant la longueur du tronçon principal 61 jusqu'à l'épaulement 70. Lors de ce déplacement, la surface convergente 63 favorise l'introduction du joint 72 et en particulier sa compression radiale.The cover 16 is then attached around the bar 12 and the external part of the body 14. When the cover 16 is pushed into the tubular extension 34, the annular seal 72 is gradually pressed along the length of the main section 61 to the shoulder 70. During this movement, the converging surface 63 promotes the introduction of the joint 72 and in particular its radial compression.

Lorsque la base 52 est en appui sur la surface externe de la paroi P, des boulons sont introduits au travers des perçages 54, immobilisant ainsi le couvercle 16. Ce dernier plaque et retient le corps 14 contre la paroi P par l'intermédiaire du joint 72 comprimé. Avantageusement, les parties saillantes des boulons sont recouvertes de capuchons isolants.When the base 52 is in abutment on the external surface of the wall P, bolts are introduced through the holes 54, thus immobilizing the cover 16. This latter plate and retains the body 14 against the wall P by through the compressed gasket 72. Advantageously, the parties protruding bolts are covered with insulating caps.

On comprend que, lorsque le couvercle 16 recouvre la paroi tubulaire 34, la goupille introduite dans les perçages alignés 40 et 42 est maintenue prisonnière à l'intérieur du dispositif passe-tige, de sorte que la barre 12 est maintenue fixe axialement.It is understood that, when the cover 16 covers the tubular wall 34, the pin inserted into the aligned holes 40 and 42 is maintained trapped inside the rod pocket device, so that the bar 12 is kept fixed axially.

Un tel moyen de retenue de la barre 12 permet de remplacer les joints 68 et 72 par simple démontage du couvercle 16, sans qu'il soit nécessaire de procéder au retrait de la goupille de retenue axiale de la barre conductrice.Such a bar 12 retaining means makes it possible to replace the seals 68 and 72 by simply removing the cover 16, without it being necessary to remove the axial retaining pin from the bar conductive.

Par ailleurs, lors du montage du dispositif passe-tige, le joint annulaire 68 est initialement disposé autour de la collerette 28. Cette dernière maintient le joint 68 en position lors de la mise en place du couvercle 16. Ainsi, il n'est pas nécessaire de procéder à une mise en place initiale du joint 68 dans le lamage 64 du couvercle 16, ce qui nécessiterait la retenue de celui-ci par mise en oeuvre d'un adhésif.In addition, when mounting the rod pass device, the seal ring 68 is initially arranged around the flange 28. This last maintains the seal 68 in position when the cover 16. Thus, it is not necessary to carry out an installation initial seal 68 in the counterbore 64 of the cover 16, which would require the retention thereof by use of an adhesive.

La lèvre périphérique externe 26 étant réalisée en un matériau déformable, celle-ci s'applique directement sur la surface externe de la barre 12, garantissant ainsi la fiabilité de l'étanchéité de la traverse.The outer peripheral lip 26 being made of a material deformable, it is applied directly to the external surface of the bar 12, thus guaranteeing the reliability of the sealing of the crosspiece.

De plus, la lèvre 26 étant prolongée par le revêtement externe isolant, le couvercle présente une bonne tenue aux agressions climatiques. Le couvercle 16 peut ainsi être disposé à l'extérieur sans protection particulière supplémentaire.In addition, the lip 26 being extended by the external insulating coating, the cover has good resistance to climatic aggressions. The cover 16 can thus be placed outside without special protection additional.

La partie du corps 14 faisant saillie vers l'extérieur par rapport à la paroi P est entièrement coiffée par le couvercle 16. Le corps peut donc être dépourvu de revêtement de protection contre les intempéries.The part of the body 14 projecting outwards relative to the wall P is entirely covered by the cover 16. The body can therefore be without weather protection coating.

Une traversée électrique telle que celle décrite ici permet le passage d'un courant d'intensité supérieure à 1000 A pour une basse tension de 380 V ou une moyenne tension de l'ordre de 20 000 V.An electrical crossing like the one described here allows passage of a current greater than 1000 A for a low voltage of 380 V or a medium voltage of the order of 20,000 V.
